This deliverable describes the preliminary version of the Data Management Plan (DMP) for the TIME4CS project. This document provides an initial summary of the main elements to take into account in the definition of the TIME4CS data management policy to be used by project partners throughout the project activities. The DMP will provide indications about the management of all the data generated during the project activities, including how data will be collected, managed, stored and made available during the project and how they will be shared upon TIME4CS completion. The DMP is a living document that will be updated during the project lifetime according to the project’s progresses and rising needs. The final version of TIME4CS DMP will be provided at the end of the project (M36) and not only will describe the procedure applied, but it will provide more details about the long-term management and preservation of project data.
